How openings in Antarctic sea ice affect worldwide climate

11. September 2017 - 19:26
In a new analysis of climate models, researchers reveal the significant global effects that seemingly anomalous polynyas, or openings in sea ice, can have. Their findings indicate that heat escaping from the ocean through these openings impacts sea and atmospheric temperatures and wind patterns around the globe and even rainfall around the tropics.

Extreme weather has limited effect on attitudes toward climate policies

7. September 2017 - 21:46
People who recently experienced severe weather events such as floods, storms and drought are more likely to support policies to adapt to the effects of climate change, according to a new study.

Warmer world may bring more local, less global, temperature variability

5. September 2017 - 19:32
Many tropical or subtropical regions could see increases in naturally occurring temperature variability as Earth warms over coming decades, a new study suggests. These local changes could occur even though Earth's global mean surface temperature variability will likely decrease because of less solar reflection from icecaps at high latitudes.

Coming soon to Montreal: The infrastructure cost of climate change

31. August 2017 - 22:13
The climate of Montreal is changing and will continue to do so at a rapidly increasing rate and with much more spatial variability in the future, according to new research.

Record-low 2016 Antarctic sea ice due to 'perfect storm' of tropical, polar conditions

31. August 2017 - 16:26
The sudden, unexpected nosedive in Antarctic sea ice last year was due to a unique one-two punch from atmospheric conditions both in the tropical Pacific Ocean and around the South Pole.

Research in ancient forests show link between climate change and wildfires

29. August 2017 - 16:10
Researchers studying centuries-old trees in South America have found a tight correlation between wildfires and a warm weather fluctuation that has become more frequent in recent decades -- and will continue to be more frequent as the climate warms.

Genetic map reveals heat tolerance traits in peas

23. August 2017 - 16:10
As the global climate changes and temperatures continue to rise, heat stress is becoming a major limiting factor for pea cultivation. A new study indicates that pea plants with some specific traits -- such as longer flowering time and higher pod numbers -- may be more resistant to heat stress. The researchers also gained new insights into the genetics of heat tolerance in pea.

Wood frogs research clarifies risks posed to animals by warming climate

19. August 2017 - 17:37
As conditions warm, fish and wildlife living at the southern edge of their species' ranges are most at risk, according to researchers who led a major collaborative study of how wood frogs are being affected by climate change.

Spoiler alert: Computer simulations provide preview of upcoming eclipse

18. August 2017 - 16:21
Scientists have forecast the corona of the sun during the upcoming eclipse. The findings shed light on what the eclipse of the sun might look like Aug. 21 when it will be visible across much of the US, tracing a 70-mile-wide band across 14 states.

Urban floods intensifying, countryside drying up

14. August 2017 - 16:29
Drier soils and reduced water flow in rural areas -- but more intense rainfall that overwhelms infrastructure and causes flooding and stormwater overflow in urban centers. That's the finding of an exhaustive study of the world's river systems, based on data collected from more than 43,000 rainfall stations and 5,300 river monitoring sites across 160 countries.

Day to night and back again: Earth's ionosphere during the total solar eclipse

10. August 2017 - 21:57
Three NASA-funded studies will use the Aug. 21 total solar eclipse as a ready-made experiment, courtesy of nature, to improve our understanding of the ionosphere and its relationship to the Sun.

Human-caused warming likely led to recent streak of record-breaking temperatures

10. August 2017 - 17:49
It is 'extremely unlikely' 2014, 2015 and 2016 would have been the warmest consecutive years on record without the influence of human-caused climate change, according to the authors of a new study.

2016 was another warm year, report confirms

9. August 2017 - 14:33
A new report confirms that 2016 was another exceptionally warm year, with global temperature having reached 0.77± 0.09 degrees C above its level between 1961 and 1990.

By the end of the century extreme weather events may affect two in three Europeans every year

7. August 2017 - 4:27
By 2100, two in three people living in Europe may be affected by weather-related disasters, according to a new study which sheds light on the expected burden of climate change on societies across Europe. The projected increases were calculated on the assumption of there being no reduction in greenhouse gas emissions and no improvements to policies helping to reduce the impact of extreme weather events (such as medical technology, air conditioning, and thermal insulation in houses).
